No, a standard HDMI cable cannot directly share an internet connection between devices.
HDMI cables are primarily designed for transmitting audio and video signals, not network data.
However, there are a couple of exceptions:
1) HDMI Ethernet Channel (HEC)
Introduced in HDMI 1.4, HEC allows for an optional Ethernet data channel over the same HDMI cable.
This means that two HEC-enabled devices connected with an HDMI cable can share an internet connection.
But only at speeds of up to 100 Mbps, which is significantly slower than modern internet connections.
However, this feature is not widely used and requires both devices to support HEC.
2) Miracast and Chromecast
While both Miracast and Chromecast can wirelessly project content from devices like smartphones or tablets to a TV, they use different technologies and offer distinct capabilities.
Look at this table:
| Feature | Miracast | Chromecast |
|---|---|---|
| Technology | Wi-Fi Direct | Google proprietary |
| Functionality | Screen mirroring | Media streaming |
| Hardware | Built-in on some devices | Chromecast dongle required |
| Internet connection | Not required | Required |
| Video quality | Lower | Higher |
| Content streaming | Limited | Wide range of apps and services |
| Device compatibility | Wider | Google ecosystem primarily |
However, In most cases, it’s much easier and more reliable to use a dedicated network connection, such as Wi-Fi or Ethernet, to share an internet connection between devices.
Because, Wi-Fi is typically the most convenient option, while Ethernet offers faster speeds and lower latency.
Hope it helps…
